This study is concerned with the state estimation and fault reconstruction problems for a class of discrete systems integral measurements under partially decoupled disturbances. The considered measurements, as functions system states over period time, reflect interval time between sample collections real‐time signal processing. Moreover, process disturbances are allowed to be in observer design. An augmented vector constructed, which consists current state, delayed additive fault, resultant...
Abstract Jointed rock masses are a common phenomenon in engineering and vulnerable to cyclic loads caused by earthquakes, blasts, traffic loads. Therefore, it is crucial comprehend the fatigue characteristics of jointed under dynamic disturbance for long‐term stability assessments structures. This paper aims investigate effects distinct joint inclinations pre‐cyclic loading on strength failure rock‐like specimens using experiments numerical simulations. The results indicate that decreases...
To explore solutions for reinforcement problems of broken rock masses in deep roadways, it is necessary to study the performance cement-based grout and its effect. In this study, grouting-reinforced specimens with different particle sizes coal were made, which revealed effect grouting on bearing capacity mechanism secondary damage instability reinforced specimens. First, was determined that appropriate water–cement ratio (W/C) meet field conditions 0.45. Second, uniaxial compression 0.45 W/C...
ABSTRACT Nonpersistent joints are prevalent in engineering rock masses and sensitive to cyclic loads induced by geological movements disturbances. Therefore, studying the fatigue mechanisms of with nonpersistent under compressive is crucial for ensuring rational design long‐term stability structures. Based on laboratory experiments, this study employed discrete element method create specimens different joints, uniaxial loading tests were conducted these maximum stress levels. The results...
Diagnosing and treating skin diseases require advanced visual skills across multiple domains the ability to synthesize information from various imaging modalities. Current deep learning models, while effective at specific tasks such as diagnosing cancer dermoscopic images, fall short in addressing complex, multimodal demands of clinical practice. Here, we introduce PanDerm, a dermatology foundation model pretrained through self-supervised on dataset over 2 million real-world images diseases,...
Goaf ground collapse has great constraints on people’s lives, property safety, and social development within the influence scope because of its concealment suddenly happening characteristics. The high-density resistivity method is used to explore goaf a quarry in Xiangtan City, Hunan Province. surface subsidence analyzed using apparent inversion section diagram comprehensive analysis results. filling water or sediment reflected as low-resistivity abnormal body, with change that significantly...
In the process of coal formation at deep seam, quality changes by geological environment. Under influence high-temperature and surrounding heat storage conditions, combined capacity oxygen is enhanced, risk spontaneous combustion enhanced. Based on law in thermal environment, industrial analysis correlation samples with different buried depth same seam were carried out. The low-medium temperature oxidation laws studied infrared spectroscopy (IR) thermogravimetric analysis. Industrial showed...
Understanding the deformation failure behavior of composite rock strata has important implications for deep underground engineering construction. Based on uniaxial compression laboratory test specimens containing holes, microscopic parameters in particle discrete element simulation are firstly calibrated. Then, mechanical properties and characteristics with holes under different confining pressures studied. The results show that dip angles have significant effects peak strength elastic...
In recent years, ecological security issues have been complex and diverse, grassland ecology has also faced problems such as overgrazing, land desertification, degradation. The protection of is an important issue. As biological resource ecology, plants play role in preventing wind sand fixation conserving water soil. Most the current related researches are concentrated on function certain or category botany. Therefore, this paper analyzes composition relationship basis analysis previous...

The theory and application of panel data modeling is an important field econometric research, but the existing theoretical assumptions are inconsistent with actual situation that generation behavior parameter distribution economic variables constantly changing; asymptotic also characteristics in practical applications, it difficult to guarantee excellent properties model estimators. This paper about development Bayesian financial data. based on MCMC sampling algorithm uses two kinds priori:...
과거 청 왕조의 발상지로서 매우 중요한 정치적· 문화적 상징성을 가졌던 중 국 심양은 근대전환기에 이르러 중국 동북 일대의 도시 가장 빠르게 도시화 · 공업화· 현대화 되었다. 교통의 발전으로 접근이 용이하고 또 넓은 평원을 보 유한 이곳에는 1910년 이후 수많은 한인들이 이주 및 정착을 시도했다. 이제 이곳은 ‘관찰이나 기행’의 대상이 아닌 ‘이주와 정착’이라는 삶의 공간으로 변하 게 된다. 최초의 이주민은 기근과 혹정(酷政)을 피해 도강을 선택한 ‘기민(飢民)’ 과도 같았던 농민들이 중심이었다. 이곳에 다른 층위의 성격이 부여된 것은 ‘한인 유림’들의 집단 이주로부터였다. 이들은 유교의 부흥을 도모하고 독립운동을 보조할 근거지를 확보하여, 한인들의 안정적인 정착과 지속을 기대하 며 도착했다. 하지만 지리에 대한 미숙, 정치적 혼란 속에서 그들의 계 획은 온전히 진행되지 못하고 좌절되었다. 이곳에서 창작된 작품들은 주 체성을 잃어가던 근대기 국내의 한시와는 차별된 작품...
